> Rowling was a progressive darling for years until she expressed disallowed sentiments outside of her fiction writing.

Really? Talents based on heredity, the portrayals of the Dursleys as fat, the renditions of other cultures, the questions of whether the goblin bankers echoed anti-Semitic stereotypes, the domestic slavery, etc. got criticism for years. She got some kudos eventually for saying Dumbledore was gay but that was late and never in the books, so it seems pretty minor to hang that theory on.
